"One of my favorite ideas is never to keep an unnecessary soldier," Thomas Jefferson wrote in 1792. Neither Jefferson nor the other Founders could have envisioned the modern national security state, with its tens of thousands of "privateers," its bloated Department of Homeland Security, its rusting nuclear weapons, ill-maintained and difficult to dismantle, and its strange fascination with an unproven counterinsurgency doctrine. In Drift: The Unmooring of American Military Power, Rachel Maddow argues that America has drifted away from its original ideals and become a nation weirdly at peace with perpetual war. She goes on to show just how much we stand to lose by allowing the priorities of the national security state to overpower our political discourse. Drift will reinvigorate the debate about how, when, and where to apply America's strength and power.
